My invention is designedfto prevent absolutely the explosion of oil lamps or stoves by reason of the generation-"thcreinof piosi've gases.

It consists-in devices, as hereinafter described and claimed, for preventingthe flame of the burner from reaching the. interior of the oil-fount by way of the wick-tube, and also for dischargin g the gas or vapor therefrom as rapidly as generated, and thereby preventing the production therein of an explosive compound.

In the accompanying drawings, Figure l is a central vertical section of a lamp embodying my invention, and Fig. 2 is a transverse section of the air-tight wick-tube in line 00 a: of Fig. 1. the formation of the wick-tube.

The first part of my invention relates to means for preventing the access of an ig-.

'niting-fiame to theoil-recep'tacle either in blowing out the lamp or from other cause. To this end I inclose the wick in an air-tight case or Wick-tube A long enough to extend from the top of the lamp down within its fonnt or oihreceptacle B nearly to the bottom thereof, and I form or fit this long wick-tube in the top of the lamp .With a gasrtight joint.

This tube will meet the ordinary wick-tube in the burner and form a continuation thereof, so that the entire tube will then extend from the burning-point of the wick down to near the bottom of the oilfo unt. The lower end of the wick-tube A is left open to admit an. inflow of oil to the wick, but being at all times below the level of the oil in the lamp when it is in customary use, it is thereby sealed with a fluid seal, eifectually preventing an inflow of gas thereto from the lamp, or an exit for an igniting-flameif' such-should possibly pass and: I dojh'er'ebydeclare that is afhll and exact description thereof, reference being had'to the"acco1n-' panyin'grl rawings, and [to the letters ofrefen' Fig. 3 illustrates a modification in reins,

down thewick-tube' This'open end the tube is moreover-guarded by a cap or cover still be effective in preventing any communication between an igniting-flame in the tube and any gas or explosive compound formed in the fount. A double guard is thus provided for the openend' of thewiclctube, otherwise, made perfectly gas-tight within the lampviz., first, a liquid seal, and, second, a safety-cap of wire-gauze, either of which will prevent or arrest the passage into or out of the tubeofe'ither an igniting flame or an explosive gas.

Where the lamp is of the type having a central-draft tube the tube may be made with double Walls to form the continuous gas-tight inclosing-chamber for the wick, (see Fig. 4,) this annular tube being extended, as above described, and as shown in Fig. 3, to reach nearly to the-bottom of. the fount.

The secondfeature of my invention to be used in combination with the gas-tight sealed wick-tube is a double ventilating-tube D, adapted to be screwed into the filling-aperture of the lamp in therefor. This ventilating appliance is constructed of a tubeD,divided by acentral longitudinal partition into two passages e f, and which is made fast in a threaded collar G, adapted-to be screwed into the threaded seat H, encircling the filling-aperture for the lamp. its upper end is bent so that the outer open ends of the two passages may be turned away from the bnrner J, and one of the passages e is made to open outwardly above the other f. The inner lower end of the double tube is beveled oil in such manner as that the opening of the one passage e shall open into the lamp at a higher level than its twin passage f. This difference iii-height between both the inner and outer opening'of the two passages will operate to induce a circulation of air through them between the outside and inside of the oil-rcceptacle, an infiowi-ngcurrent.being induced through the lower passage f, and a corresponding outflowing current through the upper passage e, so that the gases generated within the lamp will be carried 01f as rapidly as formed through thenpper passage e. The accumulation of an explosive gas within. the oil-fount is thus effectually prevented, and the lamp is stant circulation automatically established and maintained through the double ventilating-tube.

The ventilating-tube is preferably against fire byvscreens W, of wire-gauze, over both ends thereof.

I do not claim in itself as new the v combination of wire-gauze with the'wickt'ube-or ventilating-tub.e,- this being a'well-known safety device for lamps, burners, ceptacles of various'descriptions.

I claim as my invention- 1. The combination, with the fount of an oil-lamp, ot aguarded fitted wick-tube. closely fitting the wick and extending within the fouut very nearly to the bottom there oflsaid tube foaming a continuation of the ordinary wick-tube in thebu'rner' and being gas-tight from the point where it enters the fount to its termination therein, where the oil enters the tube so as to be sealed until its ,liquid contents are exhausted, and a wire-gauze covering the in? scribed. kept cool by a con- "structed of the piece and severally opening both outwardly substantially and oil-re-- V *strncted-of the ner end of said tube, substantially as de- 2. The combination, with the (Sn-remit of a .lam'p,of the single ventilating device adapted for insertion intoits filling-aperture, condouble tubes united in one and inwardly at ditferentlevels, inrthe' mannerand for the purpose herein set forth'.;

3. The combinatiom with the oil fount of a of the single ventilating device adapted for insertion into its filling-aperture, condouble tubes united in one piece and severally opening bothoutwardly and inwardly at different levels'and provided withwire-gauze, substantially in the manner larnp,
